SPEC Stage4 Clutch Kit Focus ST non-SAC


Always Free Shipping

This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. Best for drag racing, road racing, pulling, rallye and drift.

  • High clamp pressure plate

PLEASE NOTE: These kits feature a non-SAC mechanism pressure plate, which  deviating from the original design, provides a lighter rotating assembly, higher rpm capability and greater clamp load levels.
